High Water Bill: Possible Causes

How usage, billing changes, and possible leaks can all affect a bill.

A high bill can have several causes

A higher water bill isn't always a leak. Usage changes, billing cycle differences, seasonal use, and a possible leak can all affect what you owe.

Things to consider

  • Did your household usage change (guests, new appliances, gardening)?
  • Is the billing period longer than usual?
  • Are there signs of a leak (see our hidden-leak guide)?
  • Did rates or fees change on your utility statement?

Useful information to share

When you ask for help, share the amount of the increase, when you noticed it, and any signs you've seen. We can talk through whether an assessment makes sense.
